imapd - Unix, Linux Command

NAME

SYNOPSIS

DESCRIPTION

Imapd is an IMAP4rev1 server.
It accepts commands on its standard input and responds on its standard output.
It MUST be invoked by
master(8)
with those descriptors attached to a remote client connection.

Imapd reads its configuration options out of the
imapd.conf(5)
file unless specified otherwise by -C.

If the file
msg/shutdown
is created under the directory specified in the
configdirectory configuration option, then
imapd will shut down the connection, sending the first line contained in the
file to the client as the reason. New connections are denied.

If the file
msg/motd
is created under the directory specified in the
configdirectory configuration option, then
imapd will send the first line contained in the file to clients upon connect as
an ALERT message which IMAP-compliant clients are required to display.
This option serves to annoy users mostly. Unfortunately clients tend to
connect far more frequently than is apparent, causing each connection to
generate a seperate server ALERT for each connection. Many clients do not
display these properly, if they do anything with them at all.

If the directory
log/user exists under the directory specified in the
configdirectory configuration option, then
imapd will create protocol telemetry logs for sessions authenticating as
user. The telemetry logs will be stored in the
log/user directory with a filename of the
imapd process-id.
